PROBLEM TO BE SOLVED: To properly level at least two ridges, and properly detect heights of ridges.SOLUTION: A transplanter comprises: a machine body; a first planting tool; a second planting tool which is arranged to the first planting tool in a width direction and disposed in a vertically movable state to the machine body; a first detection roller which is disposed on a front side of the first planting tool, which can contact a ridge, which levels the ridge and detects a height of the ridge; a second detection roller which is disposed on a front side of the second planting tool, which can contact a ridge, which levels the ridge and detects a height of the ridge; a first attachment body whose width direction position can be changed to the machine body and on which the first planting tool is provided; a second attachment body whose width direction position can be changed to the machine body and on which the second planting tool is provided; a first support part for rotatably supporting the first detection roller; a second support part for rotatably supporting the second detection roller; and a connection part for connecting the first support part and the second support part, and capable of changing an interval between the first support part and the second support part.SELECTED DRAWING: Figure 13【課題】少なくとも2つの畝を適正に整地し且つ畝の高さを適正に検出することができるようにする。【解決手段】移植機は、機体と、第1植付具と、第1植付具と幅方向に並んで機体に上下動可能に設けられた第2植付具と、第1植付具の前方に設けられ、畝に接地可能で当該畝を整地し且つ畝の高さを検出する第1検知ローラと、第2植付具の前方に設けられ、畝に接地可能で当該畝を整地すると共に畝の高さを検出する第2検知ローラと、機体に対して幅方向の位置が変更可能で且つ第1植付具が設けられる第1取付体と、機体に対して幅方向の位置が変更可能で且つ第2植付具が設けられる第2取付体と、第1検知ローラを回転自在に支持する第1支持部と、第2検知ローラを回転自在に支持する第2支持部と、第1支持部及び第2支持部を連結し且つ第1支持部と第2支持部との間隔を変更可能な連結部と、を備えている。【選択図】図13
